I would look around a bit. There are little pockets of pre-written scripts
out there, you just need to dig them up.

Some of the scripts on may have minor issues with the daemon
flags they use, so if it doesn't work, go read the man page and compare the
flags in the script to the flags for your installed daemon.

Here is a hacked-up copy of my ./run script. Be sure to change the
"messagebus" user name after the setuidgid to the proper daemon account for
your installation. Sorry for the backslash, the word-wrap in the posting
would otherwise kill any formatting.

exec 2>&1

# must have a valid procfs
mountpoint -q /proc/ || exit 1

# create a unique identifier on each startup
dbus-uuidgen --ensure || exit 1

# start the service
exec pgrphack setuidgid messagebus \
   dbus-daemon --nofork --system --nopidfile

The daemon's runtime directory needs to exist before it is launched. The
first line after the shebang basically does that.
